Louvers

Definition

Louvers are slatted devices used in cooling towers to control airflow while minimizing water loss. They allow for the passage of air while blocking direct sunlight and precipitation, making them essential for the efficient operation of cooling towers. By optimizing airflow, louvers help enhance heat exchange processes and improve energy efficiency in these systems.

5 Must Know Facts For Your Next Test

1. Louvers help direct and optimize airflow into the cooling tower, which is crucial for maintaining effective heat transfer.
2. The angle and spacing of louvers can be designed to prevent water splash-out while still allowing maximum airflow.
3. By minimizing water evaporation and loss, louvers contribute to water conservation efforts in cooling tower operations.
4. Louvers can be designed with various materials such as plastic or metal, depending on environmental conditions and specific cooling tower requirements.
5. Regular maintenance of louvers is important as dirt and debris can obstruct airflow, reducing the efficiency of the cooling system.
